abstract = {During the last five years, serial femtosecond
crystallography using X-ray laser pulses has been developed
into a powerful technique for determining the atomic
structures of protein molecules from micrometre- and
sub-micrometre-sized crystals. One of the key reasons for
this success is the `self-gating' pulse effect, whereby the
X-ray laser pulses do not need to outrun all radiation
damage processes. Instead, X-ray-induced damage terminates
the Bragg diffraction prior to the pulse completing its
passage through the sample, as if the Bragg diffraction were
generated by a shorter pulse of equal intensity. As a
result, serial femtosecond crystallography does not need to
be performed with pulses as short as 5–10 fs, but can
succeed for pulses 50–100 fs in duration. It is shown
here that a similar gating effect applies to single-molecule
diffraction with respect to spatially uncorrelated damage
processes like ionization and ion diffusion. The effect is
clearly seen in calculations of the diffraction contrast, by
calculating the diffraction of the average structure
separately to the diffraction from statistical fluctuations
of the structure due to damage (`damage noise'). The results
suggest that sub-nanometre single-molecule imaging with
30–50 fs pulses, like those produced at currently
operating facilities, should not yet be ruled out. The
theory presented opens up new experimental avenues to
measure the impact of damage on single-particle diffraction,
which is needed to test damage models and to identify
optimal imaging conditions.},
